Several months ago I was fiddling around with a dieselized .09 Medallion. In a fit of supreme brainliness, I over compressed the day lights out of it. I ended up breaking the crank shaft and conrod/piston. I was finally able to get all the parts I needed/wanted to get it running again. It is now a Cox .09 Medallion with a Tee Dee spinner, crank shaft and piston/cylinder. When coupled with a Medallion glow head, one head gasket, Sig Champion 25 and a Cox 7x3 prop it will happily turn 13,950 RPM steadily through a complete ounce of fuel, which takes five minutes and ten seconds to burn. It is a good, steady runner. What do you guys think? Is this a good performer or did I waste the time, effort and money?

I have heard that a common mod for Tee Dee 049s is to replace the carburetor with a Medallion unit. You lose some power, maybe, but fuel draw, starting and overall handling is easier than with a Tee Dee, and you still have a lot more power than a standard Medallion.
